Hi,<br><br>Sorry by the cross post, but I'm looking for a solution for a problem I have with Torque with and without Maui.<br><br>What I need is choose nodes by CPUs in a simpler way than "-l nodes=X:ppn=Y" way. What I'm looking for is a "-l cpus=X" and let the resource manager/scheduler choose the nodes, packing the tasks in the nodes with more CPUs.
<br><br>I'm testing a heterogeneous cluster, where I have nodes with 2 CPUs single core and nodes with 2 CPUs dual core (4 CPUs). This test cluster have 3 nodes with 4 CPUs and 2 nodes with 2 CPUs.<br><br>All the jobs we run here are called automatically by an application, which calls some scripts to make the job on the cluster. If I need 16 CPUs I don't see any easy way to make a generic script, using some standard parameters, to create a "-l nodes=3:ppn=4+2:ppn=2" line :-/
<br><br>The easy way is to have something like "-l cpus=16" to the previous example, but it is possible?<br><br>Today we are using dual core CPUs but what is gonna happen when we use quad core CPUs? I see an ugly picture to my job allocation task...
